Reserves and Resources

Project

The Bisha Main deposit is a high grade VMS deposit. It is configured in three distinct layered zones - a 35 meter thick surface gold-silver oxide zone (mined out in mid-2013) immediately overlying a copper enriched supergene zone (mined out in 2016) which itself overlies a primary sulphide zone containing both zinc and copper.
